Description
Technical field
The utility model belongs to Display Technique field, is specifically related to a kind of backlight module and display unit.
Background technology
In traditional crystal display backlight source structure, be play guide effect by the gathering sill (LGP guide) on backboard 4 to the location of guide plate (LGP), light guide plate 2 be pasted onto on backboard 4, as Fig. 1 with double faced adhesive tape simultaneously.When personnel are when carrying out assembling and causing inevitable assembly failure to backlight module, the distance between LED lamp bar 1 and light guide plate 2 will be caused to exceed designing value, even if the deviation of 0.1mm also can cause the uniformity shown to have the decline of about 10%, but it is inevitable again that personnel assemble tolerance, so the difficulty of actual assembled process is comparatively large, yield is also difficult best guarantee.When distance between LED lamp bar 1 and light guide plate 2 can not keep constant, under Fig. 2 shows both relative tilt states, the spacing of LED lamp bar 1 and light guide plate 2 is not etc., now the light path of each LED is different, after the site reflection on light guide plate 2, the brightness on whole backlight module surface will be inconsistent, even if small displacement also can cause the bad of very large optics uniformity.
Utility model content
Technical problem to be solved in the utility model comprises, and for the above-mentioned problem that existing backlight module exists, provides backlight module and display unit that a kind of illumination effect is good.
The technical scheme that solution the utility model technical problem adopts is a kind of backlight module, it comprises LED lamp bar and light guide plate, and the syndeton be arranged between described light guide plate and described LED lamp bar, described syndeton has the fluting for holding the LED in described LED lamp bar, described syndeton is used for described LED lamp bar and described light guide plate to fix, and keeps the constant distance between described LED lamp bar and described light guide plate.
Fixed by syndeton between the light guide plate of backlight module of the present utility model and LED lamp bar, therefore the distance between light guide plate and LED lamp bar can effectively keep constant, thus can effectively avoid because the assembling assembly failure that causes of deviation and optics uniformity bad, meanwhile, there is the situation of LED fragmentation when can effectively prevent light guide plate and LED lamp bar to collide.
Preferably, described backlight module also comprises supporting construction, and described supporting construction is located at below LED lamp bar, for supporting LED lamp bar.
Further preferably, described supporting construction and described syndeton one-body molded.
Further preferably, described backlight module also comprises backboard, and the below of described supporting construction is located at by described backboard.
Again further preferably, described supporting construction is connected with described backboard by double-sided tape.
Preferably, be also provided with reflecting layer between described syndeton and described LED lamp bar, the reflecting surface in described reflecting layer is towards LED lamp bar side.
Preferably, also two-sided tape is provided with between described reflecting layer and described syndeton.
Preferably, the material of described syndeton is polymethyl methacrylate or PET.
Preferably, the material of described supporting construction is polymethyl methacrylate or PET.
The technical scheme that solution the utility model technical problem adopts is a kind of display unit, and it comprises above-mentioned backlight module.
Because display unit of the present utility model comprises above-mentioned backlight module, therefore its display effect is better.

Detailed description of the invention
For making those skilled in the art understand the technical solution of the utility model better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1:
The present embodiment provides a kind of backlight module, and it comprises light guide plate 2 and LED lamp bar 1, and is arranged on the syndeton 5 between light guide plate 2 and LED lamp bar 1.Wherein, this syndeton 5 has the fluting of the LED can held in LED lamp bar 1, this syndeton 5 for LED lamp bar 1 and light guide plate 2 being fixed, and keeps the constant distance between LED lamp bar 1 and light guide plate 2.
In the backlight module of the present embodiment, fixed by syndeton 5 between light guide plate 2 and LED lamp bar 1, therefore the distance between light guide plate 2 and LED lamp bar 1 can effectively keep constant, thus can effectively avoid because the assembling assembly failure that causes of deviation and optics uniformity bad, meanwhile, there is the situation of LED fragmentation when can effectively prevent light guide plate 2 and LED lamp bar 1 to collide.
Preferably, this backlight module also comprises supporting construction 6, and this supporting construction 6 is located at below LED lamp bar 1, for supporting LED lamp bar 1, thus fixing more stable between LED lamp bar 1 and light guide plate 2.Further preferably, supporting construction 6 is one-body molded with syndeton 5, therefore can improve packaging efficiency.Further preferably, this backlight module also comprises backboard 4, and this backboard 4 is located at below supporting construction 6.Still more preferably, fixing more stable in order to make between supporting construction 6 and backboard 4, both are connected by two-sided tape 3.The assembly model that the LED lamp bar 1 of the present embodiment is more traditional with the assembling of light guide plate 2 is more simple and convenient, now can adjust to minimum as much as possible by the distance between LED lamp bar 1 and light guide plate 2, better be utilized by light.
In order to avoid due to the close together between LED lamp bar 1 and light guide plate 2, the light causing LED lamp bar 1 to send can not good mixed light, and then cause the problem of display frame bad (namely hotspot), now between syndeton 5 and described LED lamp bar 1, be also provided with reflecting layer (not shown), the reflecting surface in reflecting layer is towards LED lamp bar 1 side.Now LED lamp bar issued light returns launching through reflective layer reflects, can increase the light path of light, so not only can eliminate the problem of hotspot, can also improve the utilization rate of light simultaneously, improves display brightness.Further preferably, between reflecting layer and syndeton 5, be also provided with two-sided tape 3, the structure that is making syndeton 5 and LED lamp bar 1 be integrated, now can improve packaging efficiency.
Preferably, the material of above-mentioned syndeton 5 and supporting construction 6 is high material thoroughly, both all can be preferably polymethyl methacrylate (PET) or PET (PMMA), certainly this bi-material is also not limited to, these high materials thoroughly easily operate, and embodiment is strong.
It should be noted that, the shape and size of syndeton 5 and supporting construction 6 can adjust according to the size of LED lamp bar 1.Certainly in the backlight module of the present embodiment, also comprise the well known elements such as optical film, do not describe one by one at this.
